Error: 'C123' is undifined:
PHP part of the code where readdir() is used to read all picture files, which measn that the value of $dress changes:
echo "<img src.... ......... onClick='showDress($dress)'>";
function showDress(dress) ..
SO when $dress = 9547, it works
when $dress = Q123 it does not work even if I pass it as two variables and join them as strings.
Where is the problem?
